Our invention provides an i'mpro'ved proc- I ess' of forming and holding dies for cuttlng' from paper stock or the like various different figures or Objects such as dinner cards, valentines, posters, boxes and the like. 7

Said invention also relates to an improved apparatus for use in carryingo'ut our proved process, and to such ends it consists of the novel devices and combinations of devices hereinafter described and defined in the claims. v p a I t In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views Referring to the drawings: V Fig. 1 illustrates in plan a copy sheet having printed thereon a dinner cardrepre'sent ing St. Patrick, and also,illustratinginperspective the several sections" of a die'for cutting such figures; g g h Fig. 2'is a plan View showing the copy sheet on an assembly plate, and around the figure thereon are assembled the several sections of the die held imposition by means of a plurality of clampssecured to the assembly plate;

Fig. 14: is'a sectional View taken onthe line 11-14 of Fig. "13'.

The numeral 15 indicates a rectangular" piece of paper stock hereinafter referred to as a copy sheet on which is printed a figure 16 representing" Patrick to be used as a pattern while formi'ng'a die to out such printed figures from sheets of paper stoek,-

to be used as dinner cards, one of which is shown on Fig. 7 Also cut from the paper stock with the figure 16 is a base 17 having tapered end extensions 18 which, when turned backwar d, will support said figure in an upright position but slightly backward inclined due to the tapered under edges of said end extensions.

16, base 17, end extensions 18 and producing the scoring, lines 18,-the copy" sheet 15 is placed on a fiat assembly plate 19, preferably aluminum, secured to a basef20, preferably wood or other light material, and has drilled 'semb'ly plate 19 of aluminum is that solder g To make these, end" extensions 18 bend easily'jat the proper; 7,5

- and tapped therein a plurality of longitu-' ,dinal and transverserows of holes 21. 011s of the purposes of making the assembly will not stick thereto while soldering the ends of the die sections. 1 It will be noted thatthe base 20 is of such size that the mar ginal' edge portion of the assembly plate 19 extends outward thereof, thus making it extremely easy topick upthe assembly plate 19.

The completed die forc'utting the figure 16 is indicated as an entirety by'fthe numeral 22 and comprises a plurality of sections'of steel. cutting rule, one of the lon itudinal edges of which is sharp, bent to t e contour of the figure 16, base 17, and end extensions 18, and which sections are rigidly connected by solder. As shown, the die 22 includes two horizontal base-sections 23 having converging end extensions 24 connected p of the end extensions 18.

upright side sections 26 at their abutting ends by solder a pair of connected at their abutting upper ends by solder 27 and hav ing their laterally spaced lower ends secured to the upper base sections 23 by solder 28; a pair of inside upright sections 29 having their abutting upper ends connected by solder 30 and their laterally spaced lower ends secured to the upperbase section 23 by solder 31; and a pair of upright inside sections 32 having their abutting upper ends connected by solder 33 and their laterally spaced lower ends secured to the upper base section 23 by solder 34. The baseysections 23 follow the contour of the base 17, V

and their extensions as follow the contours The side sections 26 follow-the irregular outer contour of the figure 16, and thesections29 and 32 follow certain contours of the figure 16 to make inside cuts. A relatively narrow cross-tie bar 35 has one its ends soldered to one of the sections 29 and its other end soldered to the adjacent section 26 to hold the sections 29 in their proper upright position in respect to thesections 26. A similar cross-tie bar 36 has one of its ends solderedto one of the I sections32 and its other end soldered'to the adjacent section 26 to hold the sections-32 in their proper upright position in respect to the sections26,

To prevent the upper base section 23 from cutting thefigure 16 from the base 17, said section is notched at its cutting edge between the sections 26 and the adjacent sections 29 andv 32 and between the adjacent sections 29 and 32, as indicated at 37. Scoring blades 38 for producing the scoring lines 18 extend between the base sections at the ends thereof and are rigidly secured thereto by solder 39. These scoring blades are formed from steel cutting rule and'have their sharp edges spaced above the sharp edges of the sections 23 so as to simply score and not cut the paper stock.

As each section of the die 22 is formed, it

is placed on the respective portion of the figure 16 which it represents and held position by one or more clamps 40. Each clamp 40 comprises a horizontal finger-like body and a long thumb su'ew 4:1. Said body has, at its rear end, a wide transverse sup porting. foot 42, and, at its front end, a I goose neck 43 with a transverse notch as to. xreceive and hold the upper edge portion of a die section. 7 The supporting foot 42Jis 7 adapted to rest on the assembly plate 19 or the copy sheet 15, and the thumb screw 42- extends through a longitudinal slot 45 in the body of the clamp 40 with its head impinging thereagainst and its lower end is screwed into one of the holes 21. A collar as on each thumb screw tlinward of the body of the clamp 40, holds said body and thumb screw assembled when the clamp is removed expose said hole.

After all of the sections of the die 22 are completed, assembled on thecopy sheet 15 and held in position by means of the clamp 40, the assembly plate is held in a vertical position by means of vise or otherwise and the ends of the die sections connected by solder to each other or other parts of the die sections. By thus holding the assembly plate 19, tl1e same may be very easily turned so that the soldering may be accomplished in an easy manner. After the soldering of the die sections is completed, the clamps .40 V are removed from the assembly plate 19 to 2 release thecompleted die 26, as shown in Fig. 4.

It is of course understood that in making a die, one or a plurality of sectionsof cut ting rule may be used and the joints made at any covenient place and connected by solder or otherwise. Any suitable tool or tools may be employed to bend the die sections to the j exact shape of the figure or object they are.

intended to cut. the cutting edges of the rule must In forming the die sections, always be turned towardthe copy sheet. Before the die is completely finished, the scoring blades 38 are soldered in position with their sharp edges spaced the proper distance above the cutting edge of the die 22. j It may be here. stated that at the time the .copy sheet 15 is printed, the entire number of sheets for the respective job are printed. Two or more figures or objects may be printed on a single sheet toprevent waste and to facilitate the cuttingof the figures from the paper stock, .and said figures may represent a single job or a plurality of jobs. In addition to the figure 16, there is also printed on the sheet therewith a heart-shaped figure 48; k

In Fig. 8 is shown a sheet of paper stock selected from the "job on which is printed the figures 16 and 48 and which sheet will hereinafter be referred to as a positioning sheet l9; I v j The positioning sheet a9 is placed on a wooden mounting board 50 and the die 22 is. figure 16 with its-cutting edge resting on saldsheet. The die 22 is positioned over the the positioning sheetett) and intothe mounting board 50 with the lower end of, its sleeve 52 engaging the upper edge portion of the die 22 under compression'to hold said die where positioned, More than one pin 51 I may be used, if necessary, to properly hold the die 22 in position. A die 53 for the fig or bars.

ure 48 is positioned on said figure and held Y frame to the upper surface thereof and into the'bo'dies of'the'dies 22 and 53 to a corresponding depth and allowed to set, as shown in Fig. 10. After the paraflin 56 has set, the

pins 51 are removed as they are not necessary for the reason thatthe parafiin will properly hold the dies.

Plaster ofParis'57, in plastic form, is then poured on the paraffin within the holding frame and bodies of the dies 22 and so thatlsaid frame and dies are completely .filled.- While the plaster of Paris 57 is set ting, a heating process takes place and the actionthereof on the paraffin loosens and draws the same away from the contacting surfaces of the dies 22and 53 and the depth frame 54 so that the paraffin 56 may be easily lifted from-the dies when they are removed from the depth frame 54 to expose their cutting edges, as shown in Fig- 12.

Obviously, the bodies of plaster of Paris in the dies-and surrounding the samerigidly hold said dies and secure the same to the holding frame 55. Pieces of cork 58 are 7 then glued to the plaster-of Paris 57 within the dies 22 and 53; The purpose of these cork pieces 58 is to press the paper stock from the dies after the cutting action has taken place. The holding frame 55 is then mounted in. a press, not shown, to out the figures from the printed paper stock as the same is fed to the press. After aj'ob is completed, the plaster of Paris in the holding frame maybe broken up to release the individual dies with their bodies of cementfi'om said frameso that they may be stored I away for further use and may be again mounted in a holding frame either alone or with other figures. i f

In place of the parafiin 56,21. resilient sub-- stance for instance such as used in making composition rollers, may i be substituted therefor and left in the dies to take the place of the cork 58 for projecting the figuresas they are cut by the dies; The dies are so designed as to c-utthe'figures from the-paper stockbut not remove'the same so that said figures are removed from the press with the waste material. Inplace of the cork 58, rubber or other resilient material may be used and the words plaster of Paris are herein used in a broad sense to cover any klnd of cement for securing the dies in position. The words cutting rule are also used in a broad's ense to cover any suitable material from \v hichthe dies -may be formed. f I 1 7 V The above describedprocess and apparatus have in proven highly eflicient forthepurpose had in view.j Dies formed in accordance with actual commercial usage.

ourinvention will. cut figures or designs to their exact shape and may be made to out "very intric-ate'designs and, at the same time, leave the outl nes'thereof very sharp.
